Multi-level Semantic matching of Geospatial Web Services
An Luo, Yandong Wang, Lanfang Wang, You He · 2009
The appearance of semantic Web makes the automatic discovery and invocation of geospatial Web services become possible. The key technology of automatic discovery is service matching. This paper designs a common semantic service description model, which contains four aspects as the classification of service, input/output, precondition/effect and the quality of service (QoS), to describe the geospatial semantic service by geo-ontology. Then we propose a multi-level semantic web service matching approach which matches the geospatial services on four levels. Finally, a prototype system based on the above models and methods is designed and implemented, and it demonstrates that our solution yields high-quality results under realistic situation.
